SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 425,021, dated April 8,1890.

Application filed February 10, 1890. Serial No. 339,855. (No model.)

To all whom it may concern.

Be it known that I, NATHAN A. BUCKING- HAM, a citizen of the UnitedStates, residing at Jacksonville, in the county of Morgan and State ofIllinois, have invented certain new and useful Improvements inSash-Holders, of which the following is a specification.

My present invention has special reference to that class of sash-holderswhich are used at the sides of the sashes to hold them snugly in thewindow-frame to prevent their rattling, and which are so constructed asto hold the sash firmly at any height to which it may be adjusted.

The invention consists in a certain novel construction, as will behereinafter first fully described, and then pointed out in the claims.

In the accompanying drawings, which fully illustrate my invention,Figure 1 is a perspective view of a portion of awindow, showing myimproved device in position thereon. Fig. 2 is a plan view of the upperedge of the sash; and Fig. 3 is a vertical section of a portion of thewindow, showing the holder in elevation.

Referring to the drawings particularly by letter, A designates the lowersash, B the upper sash, and O the parting-strip, all of the usual or anypreferred construction.

In practice I will employ a locking device at the center of the sashesto draw them toward each other and hold them together; but such deviceforms. no part of the present invention, as it may be of any desiredconstruction and does not affect and is not affected by the operation orconstruction of the improvements forming the subject-matter of thisapplication.

In order that my invention may be more readily comprehended andappreciated, I have illustrated a spring-bolt on the lower sash engaginga keeper-plate on the upper sash; but a cam-lever engaging a pin mightbe used or any other similar arrangement employed.

The parting-strip has secured to its opposite sides the keeper-plates DD, which are provided on their outer sides with the horizontal groovesor corrugations E, as shown. These keeper-plates may extend the entirelength of the sashes; but for ordinary purposes such lengthy plates arenot necessary.

On the upper edge of the lower sash and on the lower edge of the uppersash I secure,v

at the sides of the same, the locking-plates F F,-which may be of anydesired size, according to the size and weight of the sash, and may alsobe of any preferred configuration, provided certain features to be nowspecified are preserved. On the inner edges of the locking-plates, atthe outer ends of the same, I provide the lateral extensions G, whichproject beyond the edge of the sash and are adapted to engage thegrooves or corrugations in the keeper-plates, as shown. Thelocking-plates are further provided at their ends with the notches oropen-ended slots H, which register with the sash-cord grooves I in theside edges of the sashes, and thus provide for the uninterruptedmovement of the sashcords. This construction also enables me to prolongthe locking-plate, so that it will extend inward entirely to thewindow-frame, and thus obtain a strong hold upon the keeper-plate.

The operation of the device is thought to.

be obvious from the foregoing description,

taken in connection wit-l1 the accompanying drawings. When the sash isbeing raised or lowered, the locking-plate slips past the keeper-plate,and thus permits the sash to be readily adjusted to any desired height.After the sash has been brought to the position desired the sashes areforced together, thereby drawing the locking-plate into engagement withthe keeper-pl ate, and thereby locking the sash in its adjustedposition, so that it cannot be raised or lowered by burglars or otherunwarranted persons, and firmly supporting it against accidentaldisplacement.

My device is very simple in its construction and can be manufactured ata slight cost. It is efficient in its operation, and its advantages arethought to be obvious.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is
